On 15 September I was on the Carnival Fantasy to Bermuda. They don't call these the "Fun Ships" without good reason and thus the line's reputation for a mandatory good time is merited. The Fantasy is the oldest ship in the fleet being over 20 years old, however she doesn't look the part, largely from a 2008 refurbishment. There are many things to appreciate about this ship.
*** Activities are plentiful day and night. The day provides almost endless trivia and other games. The party goes into the early morning hours.
***The super slide in the Carnival Waterworks is one of my favorite slides anywhere...land or sea.
E181 is a 1A upper/lower which was just fine for a solo travler. I did have a hard to finding it at times and was frequently "getting lost".
